Kabeel, H.; S.M. Hussien; E.A. Ismail and T. A. Eid ( 2013). Comparative Study on The Effect of Change The Surface Irrigation to Bubbler Irrigation Systems of Fruitful "Le-Conte" Pear TreesJ. Soil Sci. and Agric. Eng., Mansoura Univ., Vol. 4 (4): 399 - 416, 2013
Abstract: The present investigation was carried out during the two successive seasons of 2011 and 2012 to evaluate the water use efficiency, vegetative and roots growth parameters, fruiting measurements, fruit quality and leaf mineral content of "Le-Conte" pear trees under the two irrigation systems. Obtained results revealed that, the surface irrigation gave the highest consumptive use followed by bubbler irrigation system. As it registered (6590 and 3311 m3/fed.) in the first season and (6398 and 3308m3/fed.) in the second one, respectively. Water consumption increased as soil moisture maintained high by surface irrigation. Monthly water use was low after February, then increased to reach a maximum during June and July then they declined again. On the other hand, bubbler irrigation system achieved an increase of water use efficiency. Data displayed obviously that, bubbler irrigation system obtained an increase in both vegetative and root growth parameters i.e., (shoot length, number of leaves/shoot, leaf area, root length, number of roots and dry weight). However, bubbler irrigation system resulted in significantly increase in fruiting parameters (fruit set %, number of fruits/tree and yield either kg per tree or ton/fed.). In addition to that, most of both physical and chemical studied fruit characteristics were improved by using bubbler irrigation system than the surface irrigation system during 2011 and 2012 seasons. Meanwhile, and leaf mineral content (N, P, and K) was insignificantly affected by both investigated irrigation systems in the two seasons of study. Finally, it could be concluded and recommended for pear growers on clay loamy soil to change surface irrigation system to bubbler irrigation system for save irrigation water with better fruit yield, fruit quality, longer root system and increasing water use efficiency.
